GLVAC 7.2 kV Series

7.2 kV medium voltage AC vacuum contactor — JCZ5 + CKG4, electrical and mechanical latching versions

The GLVAC 7.2 kV Series is a comprehensive AC vacuum contactor family for medium-voltage industrial applications. Two core technology platforms are offered: JCZ5 and CKG4 — both sharing the same current/voltage specs but differing in internal design and mounting format. Models are also split into Electrical Latching and Mechanical Latching versions.
Electrical Latching: Contactor stays closed as long as coil is energized. Mechanical Latching: Mechanical lock holds the contact closed — state preserved even without coil energy, providing energy savings and fail-safe.
The 4 current classes (160/250/400/630 A) match standard industry capacities.

TECHNICAL DIFFERENTIATORS

Why 7-2KV Series?

4 Current Classes (160-630 A)

  • Standard industry current capacities

    → Covers all 6 kV motor powers.

  • 6300 A max making capacity

    → Large motor inrush.

Mechanical Latching = Energy Savings + Fail-Safe

  • 99% energy savings

    → Coil energized only on state change.

  • Fail-safe on power loss

    → Last state preserved by mechanical lock.

JCZ5 + CKG4 Two Platforms

  • Standard (JCZ5) + Compact (CKG4)

    → For existing and new projects.

  • Electrical + Mechanical Latching

    → 4 operation profiles.
